Strongly correlated proton-doped perovskite nickelate memory devices

Koushik Ramadoss, Fan Zuo, Yifei Sun +8

We demonstrate memory devices based on proton doping and re-distribution in perovskite nickelates (RNiO3, {R=Sm,Nd}) that undergo filling-controlled Mott transition. Switching spee…

Voltage-triggered Ultra-fast Metal-insulator Transition in Vanadium Dioxide Switches

You Zhou, Xiaonan Chen, Changhyun Ko +3

Electrically driven metal-insulator transition in vanadium dioxide (VO2) is of interest in emerging memory devices, neural computation, and high speed electronics. We report on the…

Observation of a uniform temperature dependence in the electrical resistance across the structural phase transition in thin film vanadium oxide ( $V O_{2}$ )

R. G. Mani, S. Ramanathan

An electrical study of thin $V O_{2}$ films in the vicinity of the structural phase transition at $6 8^{0} C$ shows (a) that the electrical resistance $R$ follows $l o g (R)$ $\propto$ …
